ENGINE BLOCK HEATER (If Equipped)
WARNINGS
Failure to follow engine block heaterinstructions could result in propertydamage or serious personal injury.
WARNINGS
Do not use your heater withungrounded electrical systems ortwo-pronged adapters. There is a risk ofelectrical shock.
Do not fully close the hood, or allow itto drop under its own weight whenusing the engine block heater. This coulddamage the power cable and may cause anelectrical short resulting in fire, injury andproperty damage.
Note:The heater is most effective whenoutdoor temperatures are below 0°F (-18°C).
The heater acts as a starting aid by warmingthe engine coolant. This allows the climatecontrol system to respond quickly. Theequipment includes a heater element(installed in the engine block) and a wireharness. You can connect the system to agrounded 120-volt AC electrical source.
We recommend that you do the following fora safe and correct operation:
•Use a 16-gauge outdoor extension cordthat is product certified by Underwriter’sLaboratory (UL) or Canadian StandardsAssociation (CSA). This extension cordmust be suitable for use outdoors, in coldtemperatures, and be clearly markedSuitable for Use with OutdoorAppliances. Do not use an indoorextension cord outdoors. This couldresult in an electric shock or become afire hazard.
•Use as short an extension cord aspossible.
•Do not use multiple extension cords.
•Make sure that when in operation, theextension cord plug and heater cord plugconnections are free and clear of water.This could cause an electric shock or fire.
•Make sure your vehicle is parked in aclean area, clear of combustibles.

FUEL QUALITY
Choosing the Right Fuel
177
MKX (CD9) Canada/United States of America, enUSA, Edition date: 201707, First Printing
Fuel and RefuelingE161513

Your vehicle is designed to operate onregular unleaded gasoline with a minimumpump (R+M)/2 octane rating of 87.
Some fuel stations, particularly those in highaltitude areas, offer fuels posted as regularunleaded gasoline with an octane ratingbelow 87. We do not recommend these fuels.
For best overall vehicle and engineperformance, premium fuel with an octanerating of 91 or higher is recommended. Theperformance gained by using premium fuelis most noticeable in hot weather as well asother conditions, for example when towinga trailer. See Towing (page 264).
Do not use any fuel other than thoserecommended because they could lead toengine damage that will not be covered bythe vehicle Warranty.
Note:Use of any fuel other than thoserecommended can impair the emissioncontrol system and cause a loss of vehicleperformance.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuel containing more than 15% ethanolor E85 fuel.
•Fuels containing methanol.
•Fuels containing metallic-based additives,including manganese-based compounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel (using leaded fuel isprohibited by law).
The use of fuels with metallic compoundssuch as methylcyclopentadienyl manganesetricarbonyl (commonly known as MMT), whichis a manganese-based fuel additive, willimpair engine performance and affect theemission control system.
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contact anauthorized dealer to prevent any enginedamage.
FUEL FILLER FUNNEL LOCATION
The fuel filler funnel is in the spare wheelstorage tray.
RUNNING OUT OF FUEL
Running out of fuel can cause damage notcovered by the vehicle Warranty.
If your vehicle runs out of fuel:
•Add a minimum of 1.3 gal (5 L) of fuel torestart the engine.
•You may need to switch the ignition fromoff to on several times after refueling toallow the fuel system to pump the fuelfrom the tank to the engine. Whenrestarting, cranking time takes a fewseconds longer than normal.
Note:If your vehicle is on a steep slope,more fuel may be required.
